[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1 As shown, the automatic line selection device of the embodiment of the utility model includes: a mounting base 1 and a driving assembly, wherein the mounting base 1 includes a first mounting base 11 and a second mounting base 12; the driving assembly includes a first telescopic mechanism 2, a first wire clamping mechanism 3 and a second wire clamping mechanism 4, wherein the first telescopic mechanism 2 is arranged corresponding to the first mounting base 11 and the second mounting base 12, and the first telescopic mechanism is used to push the first mounting base 11 and the second mounting base 12 to separate or approach; the first wire clamping mechanism 3 is fixedly installed on the first mounting base 11, and the first wire clamping mechanism 3 includes N first wire clamping channels, and the N first wire clamping channels are sequentially arranged along the width direction of the first mounting base 11. Arrangement, that is, arranged in sequence perpendicular to the outlet direction of the cable to be selected, the second wire clamping mechanism 4 is fixedly installed on the second mounting base 12, the second wire clamping mechanism 4 includes N second wire clamping channels, and the N second wire clamping channels are arranged in sequence along the width direction of the second mounting base 12, that is, arranged in sequence perpendicular to the outlet direction of the cable to be selected, the N second wire clamping channels correspond one to one with the N first wire clamping channels, each second wire clamping channel and the corresponding first wire clamping channel are suitable for a cable to be selected to pass through, and each first wire clamping channel and each second wire clamping channel have a switchable clamping state and a loose state to clamp or loosen the cable to be selected passing through it, wherein N is an integer greater than or equal to 2.

[0032] Before the automatic line selection device is started, multiple cables to be selected can be set in the automatic line selection device. When one or more cables to be selected in the automatic line selection device are selected, all the first clamping channels in the first clamping mechanism 3 are in a loose state, all the second clamping channels in the second clamping mechanism 4 are in a clamping state, and the first telescopic mechanism 2 pushes the first mounting base 11 to separate from the second mounting base 12 (such as Figure 2 As shown); then the first wire clamping channel corresponding to the selected cable in the first wire clamping mechanism 3 enters a clamping state, and the second wire clamping channel corresponding to the selected cable in the second wire clamping mechanism 4 enters a loosened state, and the first telescopic mechanism 2 pushes the first mounting base 11 and the second mounting base 12 closer together, so that the selected cable extends from the second end of the second mounting base 12 driven by the first wire clamping mechanism 3.

[0033] When the first telescopic mechanism 2 pushes the first mounting base 11 and the second mounting base 12 to separate, all the first wire clamping channels in the first wire clamping mechanism 3 can also be placed in an intermediate state between the clamped state and the loosened state, so that while the first mounting base 11 and the second mounting base 12 are separated, all the cables to be selected can be straightened by the friction between the first wire clamping channel and the cables to be selected. When the first telescopic mechanism 2 pushes the first mounting base 11 and the second mounting base 12 to approach each other, the first wire clamping channels corresponding to the unselected cables in the first wire clamping mechanism 3 are placed in a loosened state, thereby preventing the unselected cables from bending or deforming in the device.

[0034] It can be understood that the automatic line selection device of this embodiment can realize the output of the selected cable through the cooperation of the first telescopic mechanism 2, the first wire clamping mechanism 3 and the second wire clamping mechanism 4, without the need to configure an additional power transmission system for these devices. The structure is simple and the production cost is low. Moreover, when the first telescopic mechanism 2 pushes the first mounting base 11 and the second mounting base 12 to separate, the selected cable can be straightened without the need to set up an additional straightening mechanism, thereby ensuring the straightness and accuracy of the output cable.

[0035] like Figure 1 and 2 As shown, in one embodiment of the present invention, the first telescopic mechanism 2 can be a first telescopic cylinder. The main body of the first telescopic cylinder can be mounted on the second mounting base 12, and the end of the piston rod of the first telescopic cylinder can be fixedly mounted on the first mounting base 11. When the piston rod of the first telescopic cylinder is extended backward, it can push the first mounting base 11 to move backward, thereby separating the first mounting base 11 from the second mounting base 12; when the piston rod of the first telescopic cylinder is retracted forward, it can drive the first mounting base 11 to move forward, thereby bringing the first mounting base 11 and the second mounting base 12 closer together.

[0036] In another embodiment of the present invention, the main body of the first telescopic cylinder can also be mounted on the first mounting base 11, and the end of the piston rod of the first telescopic cylinder can be fixedly mounted on the second mounting base 12, so that the piston rod can push the second mounting base 12 away from or toward the first mounting base 11. In some other embodiments of the present invention, the first telescopic mechanism 2 can also be a device such as a hydraulic cylinder capable of pushing the first mounting base 11 or the second mounting base 12 in the direction of the cable output to be selected, and this embodiment is not limited thereto.

[0037] like Figures 1 to 6As shown, in one embodiment of the present invention, the first wire clamping mechanism 3 may include a first wire clamping plate 31, N first wire pressing plates 32 and N first wire clamping cylinders 33, the first wire clamping plate 31 is installed on the first mounting base 11, and the first wire clamping plate 31 is provided with N first wire clamping grooves, the N first wire clamping grooves correspond one-to-one with the N first wire pressing plates 32, each first wire pressing plate 32 forms a first wire clamping channel with the corresponding first wire clamping groove, the N first wire pressing plates 32 correspond one-to-one with the N first wire clamping cylinders 33, and the first wire clamping cylinders 33 are used to drive the corresponding first wire pressing plates 32 to move up and down to switch the corresponding first wire clamping channel to the clamping position. Tightened state or loosened state; the second wire clamping mechanism 4 may include a second wire clamping plate 41, N second wire pressing plates 42 and N second wire clamping cylinders 43, the second wire clamping plate 41 is installed on the second mounting base 11, and the second wire clamping plate 41 is provided with N second wire clamping grooves, and the N second wire clamping grooves correspond one-to-one to the N second wire pressing plates 42, and each second wire pressing plate 42 forms a second wire clamping channel with the corresponding second wire clamping groove, and the N second wire pressing plates 42 correspond one-to-one to the N second wire clamping cylinders 43, and the second wire clamping cylinders 43 are used to drive the corresponding second wire pressing plates 42 to move up and down to switch the corresponding second wire clamping channel to a clamped state or a loosened state.

[0038] In order to avoid the first wire clamping mechanism 3 and the second wire clamping mechanism occupying too much longitudinal space, the N first wire clamping cylinders 33 can be divided into multiple first cylinder groups, and the multiple first cylinder groups are arranged sequentially along the length direction of the first mounting base 11, and the multiple first wire clamping cylinders 33 in each first cylinder group are arranged sequentially along the width direction of the first mounting base 11; the N second wire clamping cylinders 43 can be divided into multiple second cylinder groups, and the multiple second cylinder groups are arranged sequentially along the length direction of the second mounting base 12, and the multiple second wire clamping cylinders 43 in each second cylinder group are arranged sequentially along the width direction of the second mounting base 12.

[0039] like Figures 1 to 6 As shown, in a specific embodiment of the present invention, the automatic wire selection device can accommodate up to 28 cables passing through, the first wire clamping mechanism 3 includes 28 first wire clamping channels, each first wire clamping channel corresponds to a first wire clamping groove of the first wire clamping plate 31, a first wire pressing plate 32 and a first wire clamping cylinder 33, the 28 first wire clamping cylinders 33 are divided into 4 first cylinder groups, each first cylinder group includes 7 first wire clamping cylinders 33, and the first wire clamping cylinders 33 in two adjacent first cylinder groups can be staggered along the length direction of the first wire clamping groove (such as Figure 3 and Figure 4As shown); the second clamping mechanism 4 includes 28 second clamping channels, each second clamping channel corresponds to a second clamping groove of the second clamping plate 41, a second wire pressing plate 42 and a second clamping cylinder 43, the 28 second clamping cylinders 43 are divided into 4 second cylinder groups, each second cylinder group includes 7 second clamping cylinders 43, and the second clamping cylinders 43 in two adjacent second cylinder groups can be staggered along the length direction of the second clamping groove (as shown). Figure 5 and Figure 6 shown).

[0040] It should be noted that Figure 3 and Figure 4 Only the settings for the first and second cylinder groups are shown. Figure 5 and Figure 6 Only the settings of the third second cylinder group and the fourth second cylinder group are shown. The third first cylinder group and the fourth first cylinder group in the first wire clamping mechanism 3 can adopt a similar setting to the third second cylinder group and the fourth second cylinder group. The first second cylinder group and the second second cylinder group in the second wire clamping mechanism 4 can adopt a similar setting to the first first cylinder group and the second first cylinder group. This embodiment is not limited thereto. In some other embodiments of the present utility model, the first wire clamping mechanism 3 can also use a motor, hydraulic pressure, electromagnetic adsorption, etc. to switch the first wire clamping channel to a clamped state or a loosened state. This embodiment is not limited thereto.

[0041] like Figure 1 、 2 As shown in , 7 to 9, in one embodiment of the present invention, the mounting base 1 may further include a third mounting base 13, the rear end of the third mounting base 13 facing the front end of the second mounting base 12, so that the cable to be selected can extend from the second mounting base 12 to the third mounting base 13, and the wire cutting mechanism 5 is installed at the front end of the third mounting base 13, for cutting the cable extending from the third mounting base 13; the automatic wire selection device may further include: a second telescopic mechanism 6, the second telescopic mechanism 6 is arranged corresponding to the third mounting base 13 and the second mounting base 12, and the second telescopic mechanism 6 is used to push the third mounting base 13 to separate or approach the second mounting base 12.

[0042] Since the cables to be selected may have different lengths of cables extending from the third mounting base 13 during multiple selection and cutting processes, when multiple cables to be selected are selected and arranged in the automatic cable selection device, after the selected cables are extended from the third mounting base 13 under the drive of the first clamping mechanism 3, the second telescopic mechanism 6 can first push the third mounting base 13 to separate from the second mounting base 12 (e.g. Figure 7As shown), all the selected cables are extended only a short distance, and the wire cutting mechanism 5 can cut the extended cables at the same time; then the second telescopic mechanism 6 pushes the third mounting base 13 to approach the second mounting base 12, and the wire cutting mechanism 5 cuts the extended selected cables again to ensure that the cables finally cut by the wire cutting mechanism 5 are of the same length.

[0043] like Figure 2 and 3 As shown, in one embodiment of the present invention, the second telescopic mechanism 6 can be a second telescopic cylinder. The body of the second telescopic cylinder can be mounted on the second mounting base 12, and the end of the piston rod of the second telescopic cylinder can be fixedly mounted on the third mounting base 13. When the piston rod of the second telescopic cylinder is extended forward, it can push the third mounting base 13 forward to separate the third mounting base 13 from the second mounting base 12; when the piston rod of the second telescopic cylinder is retracted backward, it can drive the third mounting base 13 backward to bring the third mounting base 13 closer to the second mounting base 12.

[0044] In another embodiment of the present invention, the main body of the second telescopic cylinder can also be mounted on the third mounting base 13, and the end of the piston rod of the second telescopic cylinder can be fixedly mounted on the second mounting base 12, so that the piston rod can push the second mounting base 12 and the third mounting base 13 to separate or approach each other. In some other embodiments of the present invention, the second telescopic mechanism 6 can also be a device such as a hydraulic cylinder capable of pushing the third mounting base 13 or the second mounting base 12 in the direction of the cable output to be selected, and this embodiment is not limited thereto.

[0045] like Figure 1 、 2 As shown in , 7 to 9 , in one embodiment of the present invention, a third wire clamping mechanism 7 may be provided at the front end of the second mounting base 12 , and the third wire clamping mechanism 7 is used to clamp the selected cable extending from the second mounting base 12 and extending to the third mounting base 13 .

[0046] It is understandable that before the automatic line selection device starts line selection, the third line clamping mechanism 7 can clamp the cable to be selected. When the first telescopic mechanism 2 drives the first mounting base to move backward, the second line clamping mechanism 4 needs to clamp the cable to be selected. If the third line clamping mechanism 7 does not clamp the cable to be selected before line selection, the tension of the cable to be selected will change greatly, which may cause deformation or even damage to the cable to be selected. If the third line clamping mechanism 7 can clamp the cable to be selected before line selection, it will still clamp the cable to be selected when the second line clamping mechanism 4 clamps the cable to be selected, which can avoid excessive changes in the tension of the cable to be selected and play a protective role. When the second telescopic mechanism 6 pushes the third mounting base 13 and the second mounting base 12 to separate, the third line clamping mechanism 7 can also clamp the cable to be selected to avoid excessive changes in the tension of the cable to be selected.

[0047] In one embodiment of the present invention, the third clamping mechanism 7 can be a third clamping cylinder mounted on the front end of the second mounting base 12. The piston rod upper pressure plate of the third clamping cylinder clamps the selected cable under the action of the piston rod. In some other embodiments of the present invention, there can also be multiple third clamping cylinders, which is not limited in this embodiment.

[0048] like Figure 8 and 9 As shown, in one embodiment of the present invention, a threading plate 121 can be installed on the second mounting base 12, and the threading plate 121 can be located between the second wire clamping mechanism 4 and the third wire clamping mechanism 7. The threading plate 121 is provided with a threading groove suitable for the selected cables to pass through, so that the selected cables extending from the second wire clamping mechanism 4 can pass through the threading groove to reach the third wire clamping mechanism 7, thereby avoiding mutual interference between different selected cables.

[0049] In an embodiment of the present invention not shown in the figure, the mounting base 1 may also not include the third mounting base 13, and the wire cutting mechanism 5 can be directly installed on the front end of the second mounting base 12 to cut the selected cable extending from the second wire clamping mechanism 4 to the second mounting base 12.

[0050] like Figure 10As shown, in one embodiment of the present invention, the wire cutting mechanism 5 may include a pair of scissors 51 and a scissor drive assembly. The scissor drive assembly may include a scissor seat 52, a transmission rod 53, a pin 54, a rotating seat 55, and a scissor cylinder 56. The scissor seat 52 is fixedly mounted on the front end of the third mounting base 13. The first end of the transmission rod 53 passes through the scissors and is movable within the scissor seat 52. The pin 54 passes through a through hole in the transmission rod 53 and fixes the transmission rod 53 to the rotating seat 55. The second end of the transmission rod 53 is connected to the scissor cylinder 56. When the scissor cylinder 56 drives the transmission rod 53 to rotate clockwise about the pin 54, the first end of the transmission rod 53 drives the scissors to lift. In other embodiments of the present invention, the scissor drive assembly of the wire cutting mechanism 5 may also include a handle so that a worker can directly operate the scissors 51 to cut the cable. This embodiment is not limited to this.

[0051] like Figure 8 and Figure 9 As shown, in one embodiment of the present invention, a wire transmission platform 131 can be installed on the third mounting base 13, and a wire transmission channel suitable for the selected cable to pass through is formed between the wire transmission platform 131 and the third mounting base 13, so that the selected cable extending from the second mounting base 12 can reach the wire cutting mechanism 5 through the wire transmission platform 131, thereby preventing the selected cable from escaping from the third mounting base 13.

[0052] According to the automatic wire selection device of the embodiment of the present invention, the output of the selected cable is achieved through the cooperation of the first telescopic mechanism, the first wire clamping mechanism and the second wire clamping mechanism. The structure is simple and the production cost is low. Moreover, when the first telescopic mechanism pushes the first mounting base to separate from the second mounting base, the selected cable can be straightened, thereby ensuring the straightness and accuracy of the output cable.
